Answer:
<u>Negative Feed Back system -</u> " Some times an organ stops or interrupts a process or function in order to stabilize its self and the body, mainly the output or product of the process is lessened in order to control the situation such mechanism is known as negative feed back system."
Explanation:
<u>Negative feedback system in Lungs </u>
Now in lungs, the respiratory system maintains the normal partial pressure of the arterial oxygen and Carbon dioxide. As the partial pressure if exerted by them has a very high influence on the blood pH and can cause imbalance in the blood pH. So for this reason the negative feed back system is present.
As the body sends the message to the controlling hub of human body and then it starts the process of stabilizing the whole system back to normal by rearrangements of components or parts, along with secretion of some chemicals in the human body.
<em>Moreover a sketch is drawn which shows the feedback mechanism in a more simple way.</em>
Answer:
lava flows are very hot, thin and runny. When it cools is has a smooth to ropey texture because of the low silica content which makes it cool quickly. Pahoehoe flows creep along generally at less than 3 feet per minute but some flows have been measured at over 20 miles per hour.
Explanation:
it is A
<span>There is no primary root. Innumerable thin roots of similar size are present.</span>
The answer is a)
Individual parts within a cell that make the cell look pretty.
1. Osmosis is a process which occurs when there is a difference in solute concentration between two solutions separated by a semipermeable membrane.
2. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.
3. The semipermeable membrane limits the diffusion of solutes in the water.
4. In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. ... Water moves into and out of cells by osmosis.
5. Osmosis is basically diffusion with water. ... The most common example of facilitated diffusion is the movement of water across a cell membrane through transmembrane proteins, which requires no energy. They are simply powered by the concentration differences of the molecules between the two sides of the cell membrane.
